I have the following code, and it looks correct, and works fine, but it wont let me move on.

print "What's your first name?"
first_name = gets.chomp
first = first_name.capitalize
print "What's your last name?"
last_name = gets.chomp
last = last_name.capitalize
print "What city do you live in?"
city = gets.chomp
place = city.capitalize
print "What state/province do you live in? (Use an abbreviation)"
state = gets.chomp
place2 = state.upcase
puts "You are #{first} #{last}, and you are from #{place}, #{place2}"
